United States Patent 3,135,027 WEATHER-PROOF WINDOW -GUIDE Sam G. Squires, Box 1581, South Side Station, Springfield, Mo.

Filed Oct. 9, 1962, Ser. No. 229,294 4 Claims. (CI. 20-52) The present invention generally relates to door and window construction and more particularly to a novel means for mounting and guiding a movable glazed sash in either a door or a window.

As will be appreciated by those familiar with the art, the provision of movable sashes, particularly those of the sliding type such as the present invention is particularly concerned with, necessitates the use of reliable guide means for properly guiding the movable sash along the desired path, and effective weather-proofing means so as to properly seal the window or door. Accordingly, it is a primary object of the present invention to provide a single novel means capable of effectively functioning as both a guide means for a movable sash and a weatherproofing means.

Another object of the present invention is to provide a means which, in addition to acting as a guide for the movable sash, also constitutes the sole mounting means for the sash.

Likewise, an object of the present invention is to provide a guide for vertically sliding window sashes which is both simple in construction and of a highly durable nature.

Also, an object of the present invention is to provide a combination guide and weather-proof seal which is equally adaptable for use with a movable glazed sash in either a door or window.

A further object of the present invention is to provide a guide and mounting means enabling the mounting of a movable sash directly on the normally provided fixed sash thereby avoiding the necessity of providing specially formed Window or door frames.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part thereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 illustrates a window unit having the movable sash therein mounted and guided by the novel weather-proof guide comprising the present invention;

FIGURE 2 is a perspective view of a door having a movable sash thereon mounted in the same manner as the movable sash in FIGURE 1;

FIGURE 3 is an enlarged partial perspective view of a fixed glazed sash, a fixed screen sash, and a movable glazed sash mounted on the two fixed sashes for movement relative thereto;

FIGURE 4 is an enlarged cross-sectional view taken substantially on a plane passing along line 4-4 in FIG- URE 1;

FIGURE 5 is an enlarged cross-sectional view taken substantially on a plane passing along line 5-5 in FIG- URE 1;

FIGURE 6 is an enlarged cross-sectional view taken substantially on a plane passing along line 6-6 in FIG- URE 1;

FIGURE 7 is an exploded partial perspective view of a fixed sash and a movable sash with the guide means being retained within the movable sash;

FIGURE 8 is an enlarged perspective view of one form of the novel weather-proof guide comprising the present invention; and

FIGURE 9 is a perspective view of a second form of the weather-proof guide.

Referring now more particularly to the drawings, reference numeral 10 generally indicates a window structure comprising a frame 12, a fixed glazed sash 14, a fixed screen sash 16 vertically aligned with and abutting the fixed sash 14, and a movable sash 18 slidably mounted so as to be movable from a first position in overlapping relationship to the screen sash 16 to a second position in overlapping relationship to the fixed glazed sash 14 or any intermediate position.

The frame 12, on the inner periphery thereof, is formed with a peripheral inwardly extending flange 20 against which the fixed glazed sash 14 and fixed screen sash 16 are to be positioned in any suitable manner such as by locking pins 22 engaged within peripheral grooves 24 through suitable slots 26.

The movable glazed sash 18, of the same width as sashes 14 and 16, is slidably mounted directly on the fixed sashes 14 and 16 by mounting strips or guides 28 preferably formed of rigid plastic and being substantially I-shaped in cross section with a web 30 and transverse flanges 32 and 34 along each edge thereof.

These guide strips 28 are fixedly secured adjacent each vertical edge of the movable sash 18 with each guide 28 extending substantially the full height of the movable sash 18. This mounting of the guide strip 28 is accomplished by providing an elongated groove 36 in the inner face of the movable sash 18 adjacent each vertical edge, this groove including a narrow outer portion 38 of a width sufiicient so as to accommodate the web 30, and an enlarged inner portion 40 capable of receiving the strip flange 32 therein. The guide strips 28 are fixedly retained in these grooves 36 in any suitable manner such as by swaging in a portion of the sash 18 or by terminating the grooves 36 short of the upper and lower edges of the sash 18 as indicated in FIGURE 7.

The fixed sashes 14 and 16 are provided with similar grooves 42 and 44 for accommodating the opposite flange 34 and that portion of the web 30 which extends beyond the groove 36. However, contrary to the manner in which the strip 28 is to be fixedly received within the groove 36, this guide strip 28 is to be slidably received within the grooves 42 and 44 with there being sufiicient friction resisting this movement so as to enable the retention of the movable sash 18 in various adjusted positions between and including a first position superimposed over the screen sash 16 and a second position superimposed over the glazed sash 14. In order to enable this movement of the movable sash 18 and the strip 28 secured thereto, it will be appreciated that the lower end of the groove 42 is to be extended through the lower end of the upper glazed sash 14 as indicated at 46 in FIGURE 7, and similarly, the groove 44 will necessarily have to be extended through the upper end of the screen sash 16, thus in effect providing a continuous groove for the passage of the guide strip 28.

In addition to forming an effective means for guiding the movement of the movable sash 18, it will also be appreciated that the guide strip 28, extending substantially the full height of the movable sash 18, also provides an effective means for locking the movable sash to the stationary sashes 14 and 16 while at the same time providing a highly satisfactory weather-proof seal. In order to complete the sealing of the window structure 10, suitable means can also be provided along both the upper and lower portions of the movable sash 18, as for example a sealing strip 48 received within a groove 50 and secured in substantially the same manner as the strip 28.

With attention now being directed to FIGURE 9, it will be noted that a modified form of guide strip 52 is illustrated therein with this guide strip 52, in addition to a web 54 and flanges 56 and 58, also including two longitudinally extending oppositely projecting ribs 60 integrally formed at the longitudinal center of the web 54 and functioning so as to form a bearing surface between the 0pposed faces of the movable and stationary sashes.

As will be appreciated from the drawings, both the movable and the stationary sashes are preferably formed of metal, for example aluminum, with the inner periphery of the sashes including both an inwardly projecting periphera l flange 62 and a groove 64 spaced slightly there from, the glass or screen being positioned against the flange 6 2 and retained in position by a suitable retaining means 66' located in the groove 64 and extending slightly therebeyond.

Insofar as the door unit illustrated in FIGURE 2 is concerned, it is contemplated that both the stationary sashes 68 and 70, and the movable sash 72 be mounted and operable in the same manner as set forth in detail supra in regard to the window unit of FIGURE 1.

From the foregoing, it is considered to be readily apparent that a novel weather-proof guide and mounting means has been defined which enables the mounting of a movable sash directly upon a stationary sash or sashes so as to be movable relative thereto While at the same time maintaining a weather sealed relationship therebetween. This is accomplished by providing complementary grooves in the opposed faces of both the movable and stationary sashes with an elongated plastic guide being fixedly received within the groove of the movable sash and slidably secured within the grooves of the stationary sashes so as to enable the movement of the movable sash. Further, while not specifically brought out supra, it will be appreciated from FIGURES 7-9, that the ends of the guide strips are to be suitably bevelled on both edges thereof so as to present a reduced leading edge during both the raising and lowering of the movable sash thus facilitating this movement.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. In combination a frame, a stationary sash, a movable sash, said sashes being mounted in said frame, and guide means for guiding said movable sash relative to said stationary sash, said guide means being fixedly secured to said movable sash and slidably secured to the stationary sash for movement solely in a longitudinal direction, said sashes being orientated in parallel juxtaposed planes, said guide means being secured to the opposed faces of the sashes and constituting the sole means interlocking the sashes, said guide means consisting of two elongated strips positioned adjacent opposite edges on the movable sash, each strip extending substantially the full length of the adjacent edge and providing a seal along substantially the full length of the movable sash.

2. The combination of claim 1 wherein said strips each consist of two parallel spaced flanges and a flat web interconnecting said flanges.

3. The combination of claim 2 including grooves in each sash for the reception of the guide strips, said grooves consisting of a relatively narrow outer portion of a width substantially equal to the thickness of the webs and an enlarged interior portion conforming substantially in size and shape to the flanges.

4. The combination of claim 3 wherein said guide strips include oppositely extending ribs on said Web, said ribs being positioned midway between said flanges and orientated so as to bear on the outer surfaces of the opposed faces.
